Improvement in vapor-burmers

IMPROVEMENT iN VAPOR-BURNERS.

Specilcation forming part of Letters Patent No. 123,506, dated February6, 1872.

Specification describing an Improved Vapor- Burner, invented by ROBERTW. PARK, of Philadelphia, Pennsylvania.

Improved Vapor-Burner.

My invention consists of certain improvements, too fully explainedhereafter to need preliminary description, in vapor-burners, the saidimprovements being especially applicable to the burner for which LettersPatent were granted to me on the 31st day of January, A. D. 1871. l

In the accompanying drawing, Figure l is an exterior view of my improvedvapor-burner, Fig. 2, a sectional view ofthe same 5 and Figs. 3, 4, 5,and 6, enlarged views of part of the burner.

rlhe base or body of the burner consists of a tubular stem, A, furnishedat one side with a branch, B, the latter comunniicating with a reservoircon taining naphtha, benzine, or light oil, which can be vaporized bytheapplication oi heat so as to form an i gnitible gas. A screwvalve, G,furnished at its lower end with a handle, a, extends upward through apacked joint in the stem A, through an enlargement or annular passage,b, of the latter, and through an annular chamber formed in a tubularstem, A1, which is screwed onto the stem A, the said valve terminatingat its upper en d in a needlepoint,77 z, adapted to asi milarly-shapedseat in the stem A1. A tube, F, open at each end, is fitted over thevalve-rod C within the annular chamber of the stem A1, as best observedin Figs. 3 and 4, and is of such internal and external diameter that anarrow passage, j', shall intervene between the said tube and thevalverod and a similar passage, f', between the same and the stem A1,the object of which will be hereafter described. The tube has notches h(Fig. 5) cut in its upper aud-lower edges, in order to afford freecommunication between the annular passages at each side of the same. Asleeve, H, furnished at its upper end with outwardly-inclined wings J J,is fitted over the stem A1 in such a manner that it can be readilydetached therefrom, the said sleeve, which is intended to convey heat tothe body of the burner, extending downward to a point considerably belowthe upper end of the tube F and oil or vapor passages f and f. (SeeFigs. 2 and 3.) A tube, A2, within which is the air and vapor-mixingchamber x, isiitted within the sleeve H, rests upon the upper end of thestem A1, vand is surmounted by the tip or burner proper D. Holes c-cformed in the opposite sides of the sleeve H and tube A2, close to thebottom otl the chamber m, admit air into the latter to be mixed with thevapor before the ignition of the same. Apertures e e are formed in thetube A2 at points directly opposite the wings J J, through which jets ofignited gas-are directed onto the latter, and the said tube is indentedor bent inward at points just above these apertures, so as to forminternal deflectorsz' i, Figs. 5 and 6, for directing outward throughthe said apertures and t0- ward the wings J a suicient volume of gas.This is an important feature of my invention. Then the burner is not inuse the annular passage b communicating with the branch B, and theannular passages f and f within and surrounding the tube F, will betilled with the light oil or other iluid from the reservoir, with whichthey freely communicate. This oil is partially vaporized before lightingthe burner by heating the latter by means ot' an ignited match orotherwise, and the valve C is then lowered from its Vslot in order topermit this vapor to rise into the chamber w, there to be mixed with airentering the said chamber through the apertures c c. Aportion of thismixed air and vapor passes through the apertures ce and is ignited, thejets striking the wings J J and heating the latter. This heat istransmitted to the sleeve H, which conveys it to the body of the burner,the whole of the latter soon becoming highly heated, so that the oil,which is caused to pass in thin films through the narrow annularpassa-ges f andj" in contact with these hot metal surfaces before it canreach the outlet aperture, becomes also highly heated and completelyvaporized, escaping tinally into the mixing-chamber .r with aconsiderable degree of pressure. A portion of the mixed air and vapor,in passing upward, strikes the internal deliectors iz'and is deflectedby the same through the apertures e e and onto the inclined wings J J,playing upon the latter throughout almost their entire length andheating them almost to redness. The remainder and greater portion of theVolume of mixed air and gas emerges from the burner proper or tip D, andWhenignited forms abroad flame, closely resembling an ordinary gasjet.

Among the advantages vof my improvedburner may be mentioned the factthat access can readily be hadv to its interior for purposes ofcleansing, as all ofthe parts are detachable from each other. The sleeveH also, instead of being permanently secured to the burner,

as in my aforesaid patent of January'l, 1871,

of the'tubular stem A1, so as to form narroaT annular passages f and fcommunicating with each other at the top and bottom of the said tube, asspecified.

2. The internal deleotors z' z' formed in the tube A2 at points adjacentto the apertures e, substantially as and for lche purpose specified.

3. The sleeve H, formed in one piece, with the Win gs J, and arranged tobe fitted over the body of the burner so as to be readily detachedtherefrom, as described.

In testimomT Whereofl have signed my name to this specification inpresence of two subscribing witnesses.
